A simple operation system

A simple project for operation system class.
Thanks to jyy.
Original Project on: https://github.com/NJUOS

NJUOS supports

• a simple bootloader to boot from the very beginning
• multi-threading, provides TCB for each thread
• sleep/wakeup
• lock/unlock and semaphore to protect critical area
• message reflection
• simple device drive for keyboard, serial output and terminal

What will you see

• NJUOS needs qemu to boot
• NJUOS shows a simple terminal, the output is bound with the qemu terminal, and it echoes every letter you've typed when you press enter.

What did I contribute to

• the whole multi-threading mechanism
• lock/unlock
• message reflection
